  <div> 
	 <p>Intel&reg; Threading Building Blocks (Intel&reg; TBB) is a
		library that supports scalable parallel programming using standard ISO C++
		code. It does not require special languages or compilers. It is designed to
		promote scalable data parallel programming. Additionally, it fully supports
		nested parallelism, so you can build larger parallel components from smaller
		parallel components. To use the library, you specify tasks, not threads, and
		let the library map tasks onto threads in an efficient manner. 
	 </p>
 
	 <p>Many of the library interfaces employ generic
		programming, in which interfaces are defined by requirements on types and not
		specific types. The C++ Standard Template Library (STL) is an example of
		generic programming. Generic programming enables Intel&reg; TBB to be flexible yet
		efficient. The generic interfaces enable you to customize components to your
		specific needs. 
	 </p>
 
	 <p>The net result is that Intel&reg; TBB enables you to
		specify parallelism far more conveniently than using raw threads, and at the
		same time can improve performance.
